Hi Everyone,
I hope everyone's week is going well. Monday off, although nice, threw off my entire schedule. I feel like I've been playing catch-up most of this week. I also feel like time is moving mega fast. I'm already preparing for midterms for my math class while finishing the first exams for my science and anthropology classes. And...still waiting on the conga red for my project. I really wanted to be deep into my research by now. I also won't get much time for research next week as I'll be in California for a robotics competition. On a more positive note, I've been squeezing in time to read and finish a book. Love, Theoretically by Ali Hazelwood. It's a STEM romance, and I recommend the author to anyone who enjoys dorkish, lighthearted romance. Below is a different book I've started, and it's the first non-fiction science book I've read. Also, I would recommend it.
On Tuesday, I plated E. Coli and tested the effectiveness of 4 samples to kill the bacteria. The sample included , Aloe Vera gel (store bought), Windex, Tap water, and 70% Isopropyl Alcohol. This experiment was pretty much used to keep me busy as I haven't yet been able to start a project. However when I came in Wednesday, I found some interesting results. The zone of inhibition was basically 0 for every sample, including the isopropyl alcohol. Although the tap water, being the control, and the Windex doesn't jump out as a surprise to me, the 70% Alcohol does. Originally I had two hypothesis's on why this occurred. One being that because E. Coli is a gut bacteria and therefore is built to withstand alcohol. The second theory suggest user error such as the letting the alcohol evaporate to much before I was able to put the disk on the plate. Because of the results on Wednesday and with the first hypothesis in mind, I chose to do another plate instead with Staphylococcus. I ch...
